A total of sixty random samples of grilled chicken, chicken luncheon, beef shawerma, beef burger, yoghurt and veta cheese (10 samples of each) were collected from different cafeterias in Giza Governorate and examined bacteriologically.

Our study revealed presence of E.

Whereas Salmonella spp.

were not detected, but Staph aureus spp.

were detected by ratio of 40%, 10%, 20%, 30%, 20% and 20%, respectively in the examined samples.

While mean Yerisina were detected by ratio of 10% in each of grilled chicken, beef shawerma and beef burger samples but failed to be detected from the examined samples of chicken luncheon, yoghourt and veta cheese samples.

This study determined aerobic plate count, enterobacterial count, Bacillus cereus count and Staph aureus count in the examined samples.
